Concealment gets its own face as LIE — the cover-up, the erasure of evidence. Three verbs map to three narrative postures: truth (WORK), ambition (THINK), deception (LIE). The four-mode sim substrate is unchanged; the three verbs are the player-facing grammar over it. Resolved [OPEN]: Concealment is LIE, its own third face — not under THINK (absorbs instead of sheds, breaking THINK's rule), not under WORK (not assigned, and folding cleanup into compliance muddies both). The first-think beat still teaches WORK as the panic exit; LIE is discovered as deliberate cleanup after the dust settles.
